Homeowners typically pay for decomposed granite (DG) based on material cost, depth, installation complexity, and regional labor rates. The main cost drivers are material quality (stabilized vs loose), surface area, preparation work, and required edging or compaction. This guide provides practical price ranges in USD to help budget planning and decision making.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| DG material | $2.50 | $4.00 | $6.50 | Loose DG per square foot; stabilized variants higher |
| Area (sq ft) | 200 | 500 | 1,000 | Projected project size; larger areas reduce per‑sq ft cost |
| Base preparation | $200 | $800 | $2,000 | Grading, weed barrier, weed control |
| Edging & edging install | $150 | $600 | $1,800 | Plastic, metal, or concrete edging |
| Compaction & installation | $0.50 | $1.75 | $3.50 | Labor + equipment; includes compactor use |
| Delivery & disposal | $0 | $0.60 | $1.50 | Delivery charge may apply; disposal minimal for existing DG |
| Permits & miscellaneous | $0 | $100 | $500 | Depends on municipality and project scope |
Overview Of Costs
Typical cost range for DG projects spans broad, driven by area size and material choice. For a 300–600 sq ft patio, expect $1,500-$5,000 total with per‑sq ft pricing around $4-$8 for material plus labor. For larger driveways or pathways, budgets commonly land in the $5,000-$12,000 range. Assumptions: region, project size, soil conditions, and whether stabilization is used.
Cost Breakdown

| Edging | $0.25-$0.75/linear ft | $0.75-$1.50/linear ft | $2.50-$5.00/linear ft | Material and installation | |
| Delivery | $0-$0.50/sq ft | $0.40-$0.75/sq ft | $1.00-$2.00/sq ft | Distance from quarry | |
| Permits | $0 | $50-$150 | $400-$600 | Municipal requirements | |
| Totals | $4.0-$6.0 | $8.0-$14.0 | $15.0-$24.0 | Includes materials, labor, and extras |
What Drives Price
Material choice matters: stabilized DG costs more upfront but reduces erosion and maintenance over time. Area size and slope affect prep and drainage work; steeper grades require more compaction and edging. Soil conditions influence base preparation; rocky or soft soils increase labor and disposal needs.
Local Market Variations
Prices vary by region due to labor rates, delivery distance, and supplier pricing. In the Northeast and West Coast, expect higher per‑square‑foot costs; the South and Midwest often deliver lower ranges. Regional differences can swing totals by about ±15–25% between urban, suburban, and rural settings. The following section shows three market contexts.
Region By Region
- Urban: Higher labor and delivery costs; DG material may be similar, but setup and permits increase totals.
- Suburban: Moderate labor; typically the best balance of price and practicality for residential projects.
- Rural: Lower labor and sometimes local material sourcing reduce overall cost, though distance can raise delivery fees.
Labor, Hours & Rates
Labor for DG includes site prep, leveling, and compaction. Typical crew rates range from $50-$90 per hour for general labor, with lead installers charging on the higher end. Install time scales with area: a 300 sq ft patio may take 4–6 hours, while 1,000 sq ft pathways can take 1–2 days including breaks and edge setting. Assumptions: region, size, and site access.
Extra & Hidden Costs
Hidden fees can appear if permits are required, if heavy equipment is needed, or if drainage work is extensive. Some projects incur additional costs for weed barrier installation, geotextile fabric, or edging repairs after weather events. For stabilization options, expect a separate material and installation line item. Budget buffer recommendations: add 10–20% for contingencies.
Price By Region
- West Coast: Material $3.50–$5.50/sq ft; labor $2.50–$4.50/sq ft; typical project $3,000–$12,000.
- Midwest: Material $2.75–$4.75/sq ft; labor $2.00–$3.50/sq ft; typical project $1,800–$9,500.
- Southeast: Material $2.50–$4.25/sq ft; labor $1.75–$3.25/sq ft; typical project $1,500–$7,500.
